I am zero for three trying to get fc18 to dual boot. I have a number of systems with fc16 or fc17 currently dual booting, some with XP as well. In every case, doing a new install into a new boot and root space, NONE of the existing installed OS were recognized, only fc18 was left bootable. I also tried fedup using the existing boot partition from fc17 in hope that it would learn from the grub config file and keep the existing boots. Didn't happen.
Is this just no longer possible, or is there magic, or do I have to try and write my own grub2 stanzas, seeing that copying the ones from the fc17 boot cfg and adding them to grub2.cfg results in some boot failure mode? It seems that fc18 just won't coexist with other Linux versions, and the next machine I need to do has XP, fc4, fc9, and is currently on fc13.
Pointer to some useful info?
After a month of asking how to get dual boot working, on this list, another support list, in chat rooms, I have not had ONE SINGLE PERSON tell me that they installed FC18 and it found their other OS installs on that system, much less offered a hint how to get the other OS booted. I sadly conclude that Fedora has followed the Windows route and doesn't recognize other OS.
Tried with XP, or Win7, or BSD, or FC17, all having their own partition(s). None worked, none were recognized, pasting grub2 stanzas from previous working OS failed to boot completely.
Very sorry to see this.

Well, I have multi boot working, but not because the f18 installer helped any. A long time ago I setup a stand alone grub partition which exists only to chainload other partitions. I haven't yet converted it to use grub2, but some experiments seem to indicate it is possible:
http://home.comcast.net/~tomhorsley/game/grub2.html
Having that, I then installed fedora 18 inside a virtual machine and copied the disk image onto a real partition:
http://home.comcast.net/~tomhorsley/game/f18-install.html
This all seemed much simpler than risking the f18 installer running on my real system :-).

Well, may-be you're asking the wrong questions?
At least I don't understand what you are asking.
All I can say, I have several multi-boot installations working, comprising Fedora (17, 18), openSUSE, Ubuntu and Win8.
What I did not do, was to install F18 from scratch - I upgraded a preexisting F17 installation to F18.
Tried with XP, or Win7, or BSD, or FC17, all having their own partition(s). None worked, none were recognized, pasting grub2 stanzas from previous working OS failed to boot completely.
Sorry, I don't understand what you are trying to say.
Are you trying to utilize one single /boot partition with one single grub for a multiboot setup? From my experience, this has never actually worked. My trick to circumvent this is to use cascaded grubs (chain-loading OSes).

Can't confirm such issues. F18 hasn't stopped me from multi-booting (although the primary bootloader is from F19 Rawhide meanwhile). F18 has recognized other installations, it has added them to the boot menu, and where package "os-prober" doesn't do what I like, I've added chain-loading entries to /etc/grub.d/40_custom.

I recommend the OP to run grub2-mkconfig -o /etc/grub2.cfg When I installed F18 Anaconda did not install the other OS's for me either. The command above did the trick for me

For what it's worth I have F18 dual booting with Windows okay. I hadn't replied to your emails because it looks like you're trying to install alongside another linux (F17) and I'm not sure how to do that, particularly as the solution I did know (the one I think you were using, with separate boot partitions and the disc grub chainloading to each one) doesn't work anymore.

Please don't! That's the wrong file. /etc/grub2.cfg is a symlink, but grub2-mkconfig doesn't follow symlinks. It would replace the symlink with the new config file, but the boot loader doesn't load it from there. Run
grub2-mkconfig -o /boot/grub2/grub.cfg
instead. That's the correct command.

It still does work for me - It is exactly what I have.

So the installer worked for you and found your other OS versions and built entries for you? Never happened for me.

And with that I can see fc17 again, huzzah! The machine I tested on didn't have BSD or Windows so I can't test that, but the old fc17 shows up. I assume I have to edit the file to allow access to the older kernels if I want them, but I can play with that later.
None of this changes my opinion that the installer should at least offer this as an option, but this at least offers a way to overcome the poor installer.

I am confused as to what the issue here is, I have no problems whatsoever. My machine was quite happily booting between F17, Ubuntu 12.10 and Windows 8 without issues with the grub2 boot menus being written to the mbr on my first drive. I reformatted the boot and root partitions and installed F18 from the dvd and it picked up windows and ubuntu in its legacy grub menus (legacy grub is installed from the dvd), and when I did an upgrade from the repositories, the upgrade to grub2 picked up all my oses without me having to do anything.

Mine also installed from a DVD and all upgrades continue to work fine. Found Ubuntu on the same hard drive with no issue, did not find the Fedora 16 because I removed the hd from bios before install then put it back after install. But having said that, Fedora 18 sees the Ubuntu and Fedora16 in file system, in fact all 3 see all 3 which is great and can move and use files across all 3. regards Roger

No. As I already wrote elsewhere in this thread, I am trying to keep all OSes as separate as possible.
To achive this, I am using as a manually administrated common "/boot" partition,
grub chainloader-cascades and separate "boot" partitions for each Linux-installation, which chain-loads other OS other partitions.
Furthermore, in each Linux installations' /etc/default/grub, I have set GRUB_DISABLE_OS_PROBER=true to prevent these Linux installations' grubs to add entries for "foreign OSes".
